I was producing a multitude of different things when I finished researching the stingray interceptor. So I deleted all of the items from the queue on the ship production screen and tried to make a stingray. However, even though the queue was empty it told me "you cannot queue any more items". It give me message now when I try to build any ships, and even loading to a previous save does not let me produce any more ships here.
I think it might be related to another bug
-all living quarters full
-I try to hire someone and it says living quarters are full
-I fire someone and try to hire someone else (still full)
-I fire everybody and try to hire someone new (my empty living quarters are still full)
Note, my normal production is fine, its just the ship production that is broken.
